ARC5 — Phaseolus vulgaris

Summary

PHAVU_002G206400, designated PvARC5 on chromosome 2 of French bean (Phaseolus vulgaris), encodes a dynamin-family GTPase with GTPase activity, GTP binding, phosphoinositide binding, microtubule binding, and identical protein binding. The gene is associated with plastid and chloroplast fission, chloroplast organization, regulation of peroxisome size, peroxisome organization, mitochondrial biogenesis, response to gibberellin, circadian rhythm, seed germination, and post-embryonic development. It localizes to the chloroplast outer membrane, peroxisome membrane, microtubule, chloroplast envelope, plasmodesma, and plastid. Associations with traits include plastid development, photosynthetic ability, shoot growth angle, seed protein content, pollen fertility, high temperature stress response, disease tolerance, root morphology, and plant growth and development. Phenotypic links include chloroplast division defects, reduced chloroplast number, abnormal peroxisome division and morphology, mitochondrial size and number alterations, and slow growth with short internodes. Studies of related genes in other species connect the family to mitochondrial fission, peroxisome proliferation, pollen viability, and stress response.
